The age restriction for renting a truck from AMERCO, which operates under the U-Haul brand, typically requires renters to be at least eighteen years old. However, it is important to note that for certain larger truck sizes, the minimum age may be higher, such as twenty-one years. Additionally, drivers under the age of twenty-five may be subject to a young driver fee. This policy is designed to ensure that all renters have the necessary experience and responsibility to operate a vehicle safely. To confirm specific age requirements and any applicable fees for different truck sizes, it is advisable to check the current web page pertaining to U-Haul rentals, as policies may vary by location and vehicle availability.
